Microstructural Changes and Enhanced Current Density in Nano-sized HfO2 Added (Bi1.6Pb0.4Sr2Ca2Cu3O10)/Ag Superconductor Tapes

چکیده
The (Bi1.6Pb0.4)Sr2Ca2Cu3O10/Ag superconductor tapes have great potential for power transmission application. At relatively high temperatures, the transport critical current density (Jc) is limited by the weak pinning of magnetic flux lines. Movement of the flux lines as a result of the Lorentz force leads to the dissipation of energy and the appearance of electrical resistance. Improvement in the microstructure and addition of suitable impurities can prevent the flux from moving [1]. The objective of this work was to investigate the effect of nano-sized HfO2 on the microstructure and the critical current density of Ag sheathed Bi-2223 superconductor tapes.
